Custom Build Computer design

I do have a custom build computer loaded to my website, but I don't like it. So I need you to uninstall that one for me. First of all custom build computer is where the client can build a complete computer on my website by selecting all the components that is available, and then when finish it must go to the checkout process. I need someone to design the custom build computer from scratch, as you don't get it anywhere as a addon/plugin on the internet. It must look and work excactly as the file I included and the website I will give you. - On the top is the 4 main categories that must be followed to get to the checkout process. - On the left side is all the different components of that specific category. - If one click on the specific product then the picture must change to that product. - On the right hand side I don't know what to do, because it must be there but if you see my website it wont work. So maybe we can talk about that? - the admin area where I can add all the products. - the review and checkout page and then add it to the shopping cart. - and lots more as we can talk about that. We can talk about this, and then I will give you the website where you can excactly see how it works live. But have a look at the file that I include and you will get a good idea of what I want. Hope to hear from you soon.
